Electromagnetic Fields (EMFs): A Training Workbook for Working People published by the Labor Institute and funded by a grant from the New York Department of Labor, Occupational Safety and Health Training and Education program (19-?). Topics: electromagnetic fields, EMF, Labor Institute
The purpose of these demonstrations is to make mathematical analysis of electromagnetism take on physical meaning. Based on relatively simple configurations and arrangements of equipment, they make a direct connection between what has been analytically derived and what is observed. They permit the student to observe physically what has been described symbolically. Often presented with a plot of theoretical predictions that are compared to measured data, these demonstrations give the opportunity...

Recording of a Lecture at University of Toronto 3-10-06 with Dr. Michael Persinger and Dr. Robert Brockman. The effects of environmental and experimental magnetic fields on the human brain. A feeling of a sense presence or God experience. Topics: Persinger, Brockman, brain, electromagnetic fields, God
Published in 1989 by Prentice-Hall, this book is a useful resource for educators and self-learners alike. The text is aimed at those who have seen Maxwell's equations in integral and differential form and who have been exposed to some integral theorems and differential operators. A hypertext version of this textbook can be found here. An accompanying set of video demonstrations is available below. These video demonstrations convey electromagnetism concepts. The demonstrations are related to... Topics: electromagnetic fields, energy, theory, diagrams, calculations
Analytical and experimental studies were performed to investigate the effect of rim thickness on gear tooth crack propagation. The goal was to determine whether cracks grew through gear teeth (benign failure mode) or through gear rims (catastrophic failure mode) for various rim thicknesses. Gear tooth crack propagation was simulated using a finite element based computer program. Principles of linear elastic fracture mechanics were used. Quarter-point, triangular elements were used at the crack... Topics: PHOTONS, ELECTROMAGNETIC FIELDS, VACUUM, CAVITIES, NONLINEARITY

Cross sections and kinematic distributions for the trident production process plus or negative muon plus charge yields plus or minus muon plus electron plus positron plus charge (with charge = dipion moment and Fe) are given for beam energies of 100 to 300 GeV at fixed (electron positron) masses from 5 to 15 GeV. This process is interesting as a test of quantum electrodynamics at high energies, and in particular as a test of the form of the photon propagator at large timelike (four-momentum)...

The positron annihilation lifetime spectroscopy (PALS) using a low energy flux generator may provide a reasonably accurate technique for measuring molecular weights of linear polymers and characterization of thin polyimide films in terms of their dielectric constants and hydrophobity etc. Among the tested samples are glassy poly arylene Ether Ketone films, epoxy and other polyimide films. One of the proposed techniques relates the free volume cell size (V(sub f)) with sample molecular weight...

As a solid solution semiconductor having, a large separation between liquidus and solidus, mercury cadmium telluride (MCT) presents a formidable challenge to crystal growers desiring an alloy of high compositional uniformity. To avoid constitutional supercooling during Bridgman crystal growth it is necessary to solidify slowly in a high temperature gradient region. The necessary translation rate of less than 1 mm/hr results in a situation where fluid flow induced by gravity on earth is a...

This book deals with physical phenomena in which our attention is focussed on the on the next level in the structure of matter â the electrical structure of atoms and molecules. Electrical and radio engineering, without which the existence of todayâs civilization is unconceivable, are based on laws governing the motion and interaction of electrical particles, primarily electrons, the quanta of electricity. The main subjects of this book are electric current, magnetism and electromagnetic... Topics: physics, electrodynamics, electrons, electric current, magnets, magnetism, electromagnetic fields,...
